Specifying a generic volume serial number

Generic volume serial numbers allow you to reduce the number of entries in the VATLSTxx members. The valid generic characters are % and *; you can use any combination of these characters in an entry. If a volume serial number does not contain any generic characters, it defines only the volume with the specified volume serial number. Rules for generic volume serial numbers follow, with examples of the generic numbers and the possible matching numbers.

Rules for Generic Volume Serial Numbers: The character “*” in the generic volume serial number indicates that any character in that position and all subsequent characters are a match.

The character “%” in the generic volume serial number indicates that any single character within the volume serial number is a match to that character position.

Both symbols can appear in the same number.

You can enter the generic volume serial numbers in any order. However, if more than one generic specification can be applied to a particular volume serial, the system will find the attributes specified in the last entry with such a generic specification.

For example, an installation has the volume serial numbers WK982A and WK9BBB, and the VATLSTxx has the following entries.

WK982%,1,0,3350     ,N   STORAGE VOLUME
WK9%%%,1,1,3350     ,N   PUBLIC  VOLUME

The system will find the second entry. WK9%%% matches both volume serial number WK982A and WK9BBB.
